Walked around the southern part mid morning. Real signs of spring included 9 sand martins and 6 chiffchaffs. Remnants from the winter were also evident. A single green sandpiper flew from the marshes onto Powderham marshes. Shoveller numbers still good, I counted over 30 but only a few pintail. Wigeon numbers probably just over 120 (including I was told the American wigeon).
